I have a late 2009 i7 iMac that spends most of its time reading and swapping files from the 2TB hard drive, even though it’s only 40% full.
I want to buy an affordable (240GB/£160) Firewire external SSD, and install Yosemite on to it, then use that as my startup disc.
Will I get an appreciable jump in speed, or will I be limited by Firewire 800 speeds ?
Has any one tried this ?
